The problem with the whole turning Texas blue narrative is there is absolutely zero evidence that it is occurring. Its not as if GOP are getting slimmer and slimmer margins in the state. If that were the case then there would be justification to be worried. Also Hispanics in Texas do vote more Republican and the GOP outreach is much better than in much of the rest of the country with the only exception being Florida. True complacency is dangerous but again there is no evidence that Texas is likely to flip in the near future especially given that it is a great of attractor of those who are conservative with more moving into the state all the time.
The thing Democrats should be worried about is the fact that Texas will continue to pick up more Electoral votes as blue states lose them. Current migration trends which are often cast as the downfall of the GOP are poised to deflate the influence of large blue states. The future of blue states is is very likely to be that of economically depressed wastelands. They will be like little Cubas.
Glad to see your post.
I worry that it could be like Colo, which went from +5 Bush 2004 to +5 Obama 2012. A huge, fast swing.
Likely due to in-migration of illegals, and liberals.
